    Locating Closed Streamlines in 3D Vector Fields 

    Wischgoll, Thomas; Scheuermann, Gerik (The Eurographics Association, 2002)
    The analysis and visualization of flows is a central problem in visualization. Topology based methods have gained increasing interest in recent years. This article describes a method for the detection of closed streamlines ...

    Surface Techniques for Vortex Visualization 

    Garth, Christoph; Tricoche, Xavier; Salzbrunn, Tobias; Bobach, Tom; Scheuermann, Gerik (The Eurographics Association, 2004)
    This paper presents powerful surface based techniques for the analysis of complex flow fields resulting from CFD simulations. Emphasis is put on the examination of vortical structures. An improved method for stream surface ...

    Localized Flow Analysis of 2D and 3D Vector Fields 

    Wiebel, Alexander; Garth, Christoph; Scheuermann, Gerik (The Eurographics Association, 2005)
    In this paper we present an approach to the analysis of the contribution of a small subregion in a dataset to the global flow. To this purpose, we subtract the potential flow that is induced by the boundary of the sub-domain ...

    Analysis and Visualization of 3-C PIV Images from HART II using Image Processing Methods 

    Ebling, Julia; Scheuermann, Gerik; Wall, Berend G. van der (The Eurographics Association, 2005)
    In this paper, three-component particle image velocimetry (3-C PIV) measurements within the wake of a helicopter rotor from the HART II test are analyzed. These PIV-images are quite a challenge as the noise due to the ...

    Topology-Based Visualization of Time-Dependent 2D Vector Fields 

    Tricoche, Xavier; Scheuermann, Gerik; Hagen, Hans (The Eurographics Association, 2001)
    Topology-based methods have been successfully applied to the visualization of instantaneous planar vector fields. In this paper, we present the topology-based visualization of time-dependent 2D flows. Our method tracks ...

    Vector and Tensor Field Topology Simplification on Irregular Grids 

    Tricoche, Xavier; Scheuermann, Gerik; Hagen, Hans; Clauss, Stefan (The Eurographics Association, 2001)
    Topology-based visualization of planar turbulent flows results in visual clutter due to the presence of numerous features of very small scale. In this paper, we attack this problem with a topology simplification method for ...

    Manual Clustering Refinement using Interaction with Blobs 

    Heine, Christian; Scheuermann, Gerik (The Eurographics Association, 2007)
    The huge amount of different automatic clustering methods emphasizes one thing: there is no optimal clustering method for all possible cases. In certain application domains, like genomics and natural language processing, ...

    Detecting Critical Regions in Scalar Fields 

    Weber, Gunther H.; Scheuermann, Gerik; Hamann, Bernd (The Eurographics Association, 2003)
    Trivariate data is commonly visualized using isosurfaces or direct volume rendering. When exploring scalar fields by isosurface extraction it is often difficult to choose isovalues that convey "useful" information. The ...

    Smooth Stream Surfaces of Fourth Order Precision 

    Schneider, Dominic; Wiebel, Alexander; Scheuermann, Gerik (The Eurographics Association and Blackwell Publishing Ltd., 2009)
    We introduce a novel technique for the construction of smooth stream surfaces of 4th order precision. While common stream surface techniques use linear interpolation for generating seed points for new streamlines in the ...

    Critical Points of Gaussian-Distributed Scalar Fields on Simplicial Grids 

    Liebmann, Tom; Scheuermann, Gerik (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    Simulations and measurements often result in scalar fields with uncertainty due to errors or output sensitivity estimates. Methods for analyzing topological features of such fields usually are not capable of handling all ...
